Zero weight articulating access door

ABSTRACT

A weightless articulating door mount for a gaming machine is disclosed. The weightless articulating door mount has a four link mechanism and a cam. A biasing mechanism interacts with the weightless articulating door mount through the cam and provides a uniform force counteracting the weight of the door/monitor. With the door/monitor effectively weightless, the door may be opened and will remain in place absent any further disturbance.

BACKGROUND

The subject matter of the present disclosure relates to a door mount, and more particularly, to a gaming machine having an articulating door mount with a zero effective weight door.

In the casino gaming industry, the interior of gaming machines is secured to prevent unauthorized modification, but must be accessible to allow authorized maintenance and service. An access door is typically provided to allow access to each component within the gaming machine. Modern gaming machines use video monitors to interact with a game player and provide an immersive environment. In many gaming machines the monitors are placed on the access door and are designed to be a main point of entry into a gaming cabinet. As screen technologies advance, monitors sizes increase and the size and weight of the door increases as well.

In most cases, these access doors are opened by rotating on a hinge point. For example they may swing horizontally, or rotate vertically from a top or bottom hinge. The doors typically include a conventional linear spring push such as a strut to assist opening the access door to access the interior of the cabinet. The linear spring may hold the door open if it is of sufficient size. However, as monitors and their respective access doors on which they are mounted grow in size, the ability to lift and pivot the loaded access door is becoming more difficult, requiring larger struts. Additionally, gaming machines become prone to tipping as the additional moving weight of the monitor swings away from the gaming machine.

FIG. 5 illustrates a more detailed block diagram of various exemplary functional components of a gaming machine 100, which may be the same as or different from gaming machine 10 (as shown in FIG. 3). The foregoing description of components (e.g., display 14, player interface 50, and game controller 60) may therefore apply to the description of similar components in gaming machine 100. For instance, processor 62 may be the same as or different from 102, as described below. Similarly, memory 64 may be the same as or different from memory 103 as described below.

Accordingly, gaming machine 100 may include a game controller 101 (which may include a processor 102 mounted on a circuit board, as described in greater detail above). Instructions and data to control operation of processor 102 may be stored in a memory 103 that is in data communication with processor 102. Gaming machine 100 may include both volatile and non-volatile memory and more than one of each type of memory, with such memories being collectively represented by memory 103.

Player interface 120 also includes a payout mechanism such as a printer 109 and/or a coin output mechanism 111. The payout mechanism is configured to output a payout to a player of gaming machine 100 based on an outcome of the game (e.g., a base game and/or a feature game).

Additional hardware may be included as part of gaming machine 100, or hardware may be omitted as required for the specific implementation. For example, although buttons or touch screens are typically used in gaming machines to allow a player to place a wager and to initiate a play of a game any input device that enables the player to input game play instructions may be used. For example, in some gaming machines a mechanical handle may be used to initiate a play of the game. Persons skilled in the art will also appreciate that a touch screen can be used to emulate other input devices, such as, for example, a touch screen that can display virtual buttons that a player can “press” by touching the screen where they are displayed.

In addition, gaming machine 100 may include a communications interface, such as, for example a network card 112. Network card 112 may, for example, send status information, accounting information and/or other information to a bonus controller, central controller, server or database and receive data or commands from the bonus controller, central controller, an/or server or database. In various embodiments (e.g., embodiments that employ a player marketing module), communications over a network may be via the player marketing module—e.g., the player marketing module may be in data communication with one or more of the above devices.

In various embodiments, components of gaming machine 100 may be distributed. For example, in an embodiment, input/output devices 106, 107, 108, 109, 110, and 111 may be provided remotely from game controller 101.

One or more displays 204 may also be connected to network 201. For example, displays 204 may be associated with one or more banks 203 of gaming machines. Displays 204 may be used to display representations associated with game play on gaming machines 202 and/or used to display other representations, such as, for example promotional or informational material. Displays 204 may be the same as or substantially similar to display 14, as described above.

In a thick client embodiment, game server 205 may implement part of the game played by a player using gaming machine 202, and gaming machine 202 may implement part of the game. In such an embodiment, insofar as both game server 205 and gaming machine 202 may implement part of the game, they may collectively include a game controller. A database management server 206 may manage storage of game programs and associated data for downloading or access by gaming machines 202 in a database 206A. Typically, if gaming system 200 enables players to participate in a jackpot game, a jackpot server 207 may be provided to perform accounting functions for the jackpot game. A loyalty program server 212 may also be provided.

In a thin client embodiment, game server 205 may implement most or all of the game played by a player using gaming machine 202, and gaming machine 202 may, in essence, function provide little more than the player interface. In such an embodiment, game server 205 may include the game controller. Gaming machine 202 may thus receive player instructions and transmit those instructions to game server 205. Further, in a thin client embodiment, gaming machines 202 may be computer terminals, such as, for example, personal computers, laptop computers, tablet computing devices, smartphones, and the like running software that provides a player interface. Other client/server configurations are contemplated and are within the scope of this disclosure. Additional details of a client/server architecture may be found in WO 2006/052213 and PCT/SE2006/000559, the disclosures of which are incorporated herein by reference in their entireties.

One or more servers may be provided to assist in the administration of gaming system 200. Such servers may include, for example, a gaming floor management server 208, and a licensing server 209 to monitor the use of licenses relating to particular games. An administrator terminal 210 may be provided to allow an administrator to run network 201 and the devices connected to network 201.

Gaming system 200 may communicate with other gaming systems and/or other local networks, such as, for example a corporate network, and/or a wide area network such as the Internet Communications may be filtered through a firewall 211.

Persons skilled in the art will appreciate that in accordance with known techniques, functionality at the server side of network 201 may be distributed over a plurality of different computers. For example, elements may be run as a single “engine” on one server or a separate server may be provided. For example, game server 205 may implement a random number generator engine. Alternatively, a separate random number generator server may be provided. Further, persons skilled in the art will appreciate that a plurality of game servers may be provided to implement different games or a single game server may implement a plurality of different games as required by the terminals.

In an exemplary embodiment, a player may place a wager using the game play mechanism 56. A game (or game session) may be initiated in response to placement of the wager, a plurality of symbols randomly drawn, and a game (or game session) outcome determined based upon the symbols drawn. A game outcome may be compared to a pay table (which may be stored in a computer memory) to determine a payout or award (also referred to herein as a win entitlement). Persons skilled in the art will appreciate that a player's wager can be varied from game to game dependent on player selections.

In various embodiments, a wager may include a selection of a number of lines to be played during a game session. Such lines may include an interconnected combination of symbol display positions. Each selected line may be evaluated to identify winning combinations of symbols. A pay table (e.g., a pay table stored in memory 64) may be referenced to identify a payout or award based upon an identified winning combination of symbols. In various embodiments, an award may be multiplied or increased by a multiplication factor as well.

In an exemplary embodiment, gaming machine 202 may generate an award that is not based solely upon a number of a lines selected. For example, “scatter” pays (e.g., randomly selected awards that are not identified based upon a plurality of adjacent symbols) may be awarded independently of a player's selection of pay lines.

In many gaming machines, monitors are placed on the access door and are designed to be a main point of entry into the gaming cabinet for service and repair. Having the monitor mounted on the access door enables access to the monitor and the door to be concealed around the monitor.

FIG. 7 illustrates an exemplary gaming machine 700 having a zero effective weight articulating door. Gaming machine 700 has a cabinet 704 with a monitor 702 acting as an access door. Monitor 702 is secured to cabinet 704 by way of an articulating door mount as will be described below. Although aspects of the exemplary embodiment will be described in reference to a monitor, it should be understood that the embodiments are applicable to weighted doors and combinations of doors and monitors. When installed, monitor 702 moves between a first position covering doorway 708 inhibiting access to interior 706 of cabinet 704 and a second position in which doorway 708 is exposed, allowing access to interior 706.

FIG. 8 illustrates exemplary gaming machine 700 of FIG. 7, but with monitor 702 removed to show interior 706 of cabinet 704. Monitor 702 couples to articulating door mount 710 through conventional means such as bolts and screws. FIG. 9 illustrates monitor 702 and articulating door mount 710 removed from cabinet 704 for clarity. Articulating door mount 710 is configured to be secured to cabinet 704 through conventional means, such as a bolt or screw through mounting holes in bracket 705. FIG. 10 illustrates the back side of monitor 702 with articulating door mount 710 removed. Monitor 702 has a mounting surface 703 configured to be secured to articulating door mount 710.

FIG. 11 through FIG. 13 illustrate exemplary articulating door mount 710, but with monitor 702 removed for clarity. FIG. 11 illustrates articulating door mount 710 in a lowered or closed position, FIG. 12 illustrates articulating door mount 710 in a partially open position, and FIG. 13 illustrates articulating door mount 710 in a raised or open position. Articulating door mount 710 secures monitor 702 to cabinet 704 and supports monitor 702 when accessing interior 706 of cabinet 704. At least one linkage assembly 712 is used to guide monitor 702 up and down in a determined path. Multiple linkage assemblies 712 may be used to improve rotational stability of monitor 702. Additionally, linkage assemblies 712 may share components. For example, a link may be elongated horizontally and span multiple linkage assemblies. Exemplary articulating door mount 710 has two linkage assemblies 712, although more or less linkage assemblies are possible.

Linkage assembly 712 has a stationary link 716, a door link 714, an upper link 718, and a lower link 720. A biasing mechanism 726 biases door link 714 upward through a cam 724. Biasing mechanism 726 is coupled to a link and cam 724 is coupled to an adjacent link. In the exemplary embodiment, biasing mechanism 726 is coupled to stationary link 716 and cam 724 is integrated in lower link 720. In other embodiments, the biasing mechanism may be coupled to any one of the links and the cam to an adjacent link. For example, if a biasing mechanism were coupled to lower link 720, cam would be coupled to either stationary link 716 or door link 714.

Each link is secured to an adjacent link through a rotatable coupling. A rotatable coupling is defined as a connection that secures two points of adjacent components together preventing translation but allowing rotation. A hinge is an example of a rotatable coupling that allows rotation in a single direction. A ball and socket is an example of a rotatable coupling that allows rotation in a three directions. In the exemplary embodiments, the links are secured together by the shaft of a bolt passing through eyeholes in the links allowing the links to rotate about the axis of the shaft.

Stationary link 716 is configured to be secured to cabinet 704. Stationary link 716 may be secured to cabinet 704 through bolts 722 or other conventional fasteners. Stationary link 716 may be removed from cabinet 704 for ease in assembly and maintenance by removing bolts 722. Door link 714 is configured to be coupled to monitor 702 and moves at each end relative to cabinet 704. Door link 714 may be a separate link secured to monitor 702 or a door, or door link 714 may be the door or monitor itself. For example, door link 714 could be a rigid door having an upper tab with an eyehole and a lower tab with an eyehole for connection to a link. Upper link 718 is rotatably coupled to door link 714 through a first rotatable coupling 715 and to stationary link 716 through a second rotatable coupling 717. Similarly, lower link 720 is rotatably coupled to door link 714 through a third rotatable coupling 719 and to stationary link 716 through a fourth rotatable coupling 721.

Opposing links may be of equal length. For example, upper link 718 and lower link 720 may be the same length, and door link 714 and stationary link 716 may be the same length. In such embodiments, door link 714 and stationary link 716 remain parallel throughout their movement. Thus, monitor 702 mounted to door link 714 would remain at the same angle as monitor 702 is lifted.

Biasing mechanism 726 is configured to bias door link 714 upward. Biasing mechanism 724 may bias door link upward directly, or more commonly through another link. For example, a torque bias on either upper link 718 or lower link 720 will bias door link 714. Biasing mechanism 726 may be a spring and in the exemplary embodiment is a torsion spring.

Biasing mechanism 726 interacts with cam 724 to provide a relatively constant bias to door link 714, such that the weight of monitor 702 is supported at each position of door link 714. Having a relatively constant bias results in a monitor that has the sensation of being weightless. In the exemplary embodiment, a torsion spring biases arm 728 to rotate about torsion spring. Arm 728 contacts cam 726 and biases cam 724. Because cam 724 is coupled to lower link 720, contact with the arm 728 provides a torque bias to lower link 720 which then biases door link 714 upward.

The torsion spring is advantageous in that it may have a relatively constant force when compressed. A conventional spring, such as a linear spring requires a linearly increasing force to compress it. As a result, a door biased by a linear spring may have a bias force much greater than the weight of the door and monitor when it is compressed, causing them to lift or spring when the door is opened. A torsion spring, in comparison, may have a relatively constant torque throughout its range of motion putting a uniform pressure on the linkage. The force needed to lift the door is therefore relatively constant. By reducing the effective weight of the monitor door, an operator may open and close the door without having to overcome an additional force need to keep the door open.

In some embodiments, biasing mechanism 726 is made from several small rods in torsion. The spring rate of the biasing mechanism 726 is determined by the number and size of the small rods. If there is a failure in a rod of the biasing mechanism 726, the spring rate is only reduced by a small percent preventing monitor 702 from fully closing. This protects the operator from being injured from a falling monitor 702 in any position. One benefit of using a biasing mechanism 726 to give zero weight to monitor 702 is that all required variables are constant, so the operation life of the cabinet door can be calculated without addition inputs like shelf life, opposing force and environmental factors. By determining the operation life, the cabinet door can have a determined replacement schedule past the operation life of the cabinet making the door operation service free.

Linkage assembly 712 prevents monitor 702 from swinging out excessively while maintaining monitor 702 in an upright position during movement. As can be seen in a comparison of FIG. 10 and FIG. 12, when monitor 702 is raised to its maximum vertical extent, its horizontal displacement is minimal compared to a conventional swinging door.

Cam 724 may be a separate component mounted to a link, or in some embodiments cam 724 may be integrally formed with a link. For instance, in the exemplary embodiment, cam 724 and lower link 720 are a single piece. Cam 724 provides a smooth transition surface biasing mechanism 726 apply its bias. Biasing mechanism 726 pushes cam 724 with enough force to counteract the weight of monitor 702 and linkage assembly 712 allowing monitor 702 to become effectively weightless. Because monitor 702 is essentially weightless, monitor 702 remains in any position at which it is left. For example, if a user moves it halfway up, it remains halfway up absent any further force.

FIG. 14 through FIG. 16 are side views of articulating door mount 710 and illustrate the operation of biasing mechanism 726 and cam 724. FIG. 14 illustrates articulating door mount 710 in a closed position, FIG. 15 illustrates articulating door mount 710 in a mid-position, and FIG. 16 illustrates articulating door mount 710 in an open position. In each of these positions, cam 724 and biasing mechanism 726 cooperate to provide a relatively constant upward force balancing the weight of monitor 702. The force exerted by biasing mechanism 726 is related to the effective radius of cam 724. When cam 724 has a low effective radius, there is little relative preload on biasing mechanism 726 and the bias is minimal. When cam 724 has a higher effective radius, the preload of biasing mechanism 726 increases and the bias force is increased.

In FIG. 14, the weight of monitor 702 is nearly tangential to the lower link 720, and a minimal amount of torque is required to counteract the weight of the monitor 702. In this position, cam 724 has a minimum effective radius and provides little pre-load to biasing mechanism 726. In FIG. 15, the weight of monitor 702 is perpendicular to lower link 720 and the greatest amount of torque is required to balance the weight of monitor 702. In this position, cam 724 has a greater effective radius pre-loading biasing mechanism 726. This in turn results in a greater force being applied to the lower link 720, balancing the weight of monitor 702. In FIG. 16, monitor 702 is at its maximum height. The weight of monitor 702 is again nearly tangential to the lower link 720 and less preload is required from biasing mechanism 726 to support monitor 702. Thus cam 724 has a lower effective radius in this position. Additionally, cam 724 includes a stop 728 preventing monitor 702 from being over extended.

Monitors of varying weight may be supported using the described system. Different weights will require biasing mechanisms having different spring constants. For example, a lighter monitor may be supported by removing some of the rods from the torsion spring, while a heavier monitor may be supported by adding rods to the torsion spring. Because the range of motion would not change, the cam may be reused in such embodiments. If a different biasing mechanism were used, or if the geometry of the linkage assemblies were changed, it may be necessary to use a different cam shape. In general, in areas requiring a greater bias, the cam has a greater radius to preload the biasing mechanism, while in areas requiring lower bias; the cam has a reduced radius.
